Fedora :: Benefits / Reasons To Upgrade To F15
Jun 8, 2011What are the benefits to upgrading to F15 from F14 if any? Has there been some huge step forward in performance, security or some other reason that makes it worth while to upgrade? I know many people make the move simply because they wish to have the latest and greatest, but is there any reason specifically to upgrade to the latest and greatest?

Jan 22, 2011I am using 10.04 LTS Lucid, and I notice the free space of root is getting smaller and smaller.
Five months ago, there was about 3.9GB free space of root, but now it is only 1.6GB. I always run sudo apt-get autoremove and sudo apt-get autoclean every time the update is finished, and also use Bleachbit to clean the system, but both are useless.
I never faced such problem with older versions of Ubuntu, is there any measure to fix it?

1. There is not any .deb in the /var/cache/apt/archives.
2. The total content of /var/log is only 167.6 MB, that won't be a problem.
Fedora :: Benefits Of Running Strictly KDE Or Strictly Gnome ?
Jul 2, 2011I notice that a lot of you speak of running a 100% KDE setup for your personal computers. What are the advantages of this?
I see the major disadvantage to be that I wouldn't be able to just run what I want when I want. I don't see how much else could out weigh such a thing either.
I assume stability and compatibility and system resources are all very good reasons against it possibly. But really, at this stage in the game, with the speed of computers why not? Plus I haven't noticed too many, if any compatibility issues, it's all the same kernel right?
Fedora :: Mounted ISO Is Smaller Than Actual ISO?
Jul 5, 2011I have an ISO of a game I own that shows up as 5gb. When I mount the ISO like this:
mount -t iso9660 -loop game.iso /mnt/loop
and go to /mnt/loop and execute
du -hs
it returns 2.5gb. Examination of all the files and directories in /mnt/loop does indeed add up to 2.5gb. So my question is what happened to the rest of it? Does the 5gb ISO contain a bunch of empty space? Should I try to burn it to a DVD and see what happens or should I burn it to a dual layer disc? I don't want to waste a dual layer disc if I don't have to.

View 1 Replies View RelatedRed Hat :: Kerberos Versus LDAP SSL - Benefits?
Apr 21, 2011I am confused with the concept of Kerberos and LDAP SSL. I am in the midst of integrating my Unix box with the Active Directory hence the use of PAM_LDAP method. I understand that since it's non-secure transmission hence We use Kerberos to authenticate. If we already used kerberos to authenticate i.e. it means that the username/password is not transmitted in clear text. Why we still need LDAP SSL? What is the benefit?
View 3 Replies View RelatedUbuntu Networking :: IRC Channels - Benefits Of NFS Over CIFS?
May 14, 2011I was asking around in some IRC channels earlier trying to develop some thoughts on how NFS is better than CIFS. I set up a FreeNAS file server, and that's where all of my data now resides on a pair of raided drives. That way my main desktop, which is kind of a power hog gaming rig, can be powered off since I pretty much live on my laptop now. Anyway, I began to tinker with CIFS and NFS. Since some family members in the household use Windows, I definitely need CIFS. But I wanted to bounce back to NFS too and check it out.
While I do think it's nice I don't have to worry about authentication to the NAS box when using NFS, it's still a little scary. Being that it's more of a trust method instead of actual authentication, truthfully all a user needs to get into your data is the path to your NFS share and a matching UID. I mean, am I wrong by saying this? Sure, it may seem like NFS is convenient, but this angle of it is a little scary. I just don't feel like that screams "secure."
On the flip side, you have CIFS, which uses a user authentication level. So I hit my little shortcut to my NAS and it asks me who I am. I log in and bam, I have connection. I can browse other folders on the share, etc. This is convenient because I do have a "public" share on here with a generic user. That way if friends come over and want to transfer something to me, I have them drop it in the public share and I later transfer it accordingly. Since there is a user level authentication, this to me seems a little more secure.
Speed wise I was a little concerned, as some users have said NFS is faster than CIFS. Well, they might be right. But I did a few bench tests here on my laptop, using the same exact share except one with CIFS one with NFS. I stayed in the exact same location and transferred the same 300mb file in each instance.
NFS - 1.7mb/s
CIFS - 1.5/mb/s
Not exactly enough to warrant a huge argument over, so I leave that argument along the road to be forgot about since it doesn't really have any bearing on this situation. I like things about both NFS and CIFS. I just want to know why is it "not optimal" to use a full blown CIFS setup even if you're using 100% Linux systems.
Ubuntu Servers :: Extra Benefits / Features Of UEC Over Virtualization
Apr 3, 2010I have set up UEC and have installed the store images. I have seen that we can create and run instances which are similar to virtual machines. We can utilize virtualization and create virtual machines and thereby fully utilize the server. Not sure what extra benefits or features can be achieved using cloud (say UEC). I suppose I am missing something. Kindly let me know how cloud adds more value than server virtualization.

Jul 21, 2011Since I have never had the need to create one, the first time I encounterd it I asked myself: what is it?I was looking for MySql installation guidelines on mysql.com, when, reading them, I found this command:shell> useradd -r -g mysql mysql.Now, I read the man page of useradd looking for explanation about -r option, but I didn't found it useful.It just says that -r options creates a System account, but it doesn't say anything else.So my question is: what is a system account? Few lines under the command it says:"Because the user is required only for ownership purposes, not login purposes, the useradd command uses the -r option to create a user that does not have login permissions to your server host."What would be the benefits if mysql user has not login permission?
View 6 Replies View RelatedServer :: Benefits To Creating Multiple Partitions For RAID1 Setups?
Dec 21, 2010I am rebuilding a bunch of servers and want to do it right. They are Dell R200s and R300s with on-board LSI SAS1068E SCSI controllers with 2 SATA drives. The only RAID level supported on these cards is RAID 1. So, to the server, we have 148GB of space to deal with. They currently run 32-bit Ubuntu 8.10; I will be installing x64 Ubuntu 10.04.
I have always seen that it is best practice to partition in such a way that /boot, /var/log, /temp, and /home for example are separated out from /. Usually this is on a RAID5 or higher box. Is there any benefit to doing that sort of thing on a RAID1 box? I realize that this is in some ways a matter of opinion, but I would like the opinion of folks with experience. I'm pretty new to Linux in general.
The main services running on these boxes are Apache2, Tomcat6, MySQL, and Java.

Ubuntu :: How To Get Smaller UI Elements
Sep 14, 2010I cannot reduce the size of all icons, context menu items etc.For example, I need to do some minor programming for the university. And this is how Eclipse Aptana RadRails look on a netbook: [URL] UI takes up to 70% of screen space, and the IDE is barely usable now. On Windows it looks like [URL] I tried some gnome themes but they all are of the same size. Is there any way how I can reduce the size at least for the whole system (nautilus etc)? If there is a way how I can apply 'nanoized' theming for desired applications only.
